Abstract
Abstract The physicochemical properties of eight hazardous waste samples (S1, S2, S3, S4, S5, S6, S7 and S8) obtained from Heilongjiang Province were analyzed to assess the suitability of landfill directly. The results showed that the wet content of eight samples was according with the landfill standards. However, some parameters of the samples S1, S2, S5 and S6 were not up to the standards. In addition, the Fe, Mn, Zn, Ni, Cr, and Be content in samples S1 and S5 exceeded the landfill standard limit. The sources of heavy metals were identified by analysing the correlation of the Zn, Mn and Ni concentration in different samples. The result showed that the correlation coefficient of the Zn, Mn and Ni concentration exhibited a significant level, which indicated that the metal Zn, Mn and Ni might originate the same source. The inorganic fluoride content in all samples did not exceed the landfill control standard, whereas the cyanide concentration was as 244.80∼2 692.76 times as the control limits except S1. In addition, benzene series were detected in some samples except S6 and S7, indicating that these samples needed pre-treatment before landfill.
